Description of the problem: •component/system that failed: the engine starter, which is subject to an open recall issued September 23, 2025. The starter was not replaced during a service visit. The vehicle no longer exists due to the fire, but the VIN and service records are available for inspection. •safety risk: the starter malfunction caused the vehicle to catch fire while parked, creating a serious safety risk to myself, my child, and others nearby. •problem reproduction/confirmation: the fire and defect were confirmed by BMW’s inspection as originating from the starter irregularity tied to the recall. •inspections: the vehicle was inspected by BMW north America’s engineering team after the fire, and insurance representatives confirmed the total loss. •warning signs prior to failure: there were no warning lamps, messages, or symptoms indicating the starter defect before the fire. Additional context: the vehicle was serviced at an authorized BMW dealership on December 3, 2025. I was not informed of the recall, and the starter was not replaced. The vehicle caught fire on December 19, 2025, resulting in a total loss. While my insurance resolved the acv, this incident was caused by BMW’s recall-related defect and procedural failure. I have escalated this matter to BMW north America and am requesting a resolution that restores me to a comparable position (replacement vehicle or financial support). Official confirmation: BMW north America confirmed in a confidential letter that the fire originated from the starter defect tied to the open recall. This letter is available for review upon request.

25v-636 we received a recall notice for the above notice over a month ago. No further communication has been sent from BMW in the status of new part availability and they refuse to assist with accommodations because of the scale of the recall. The letter clearly states that there is a fire risk and to not park near structures. This leaves almost everybody who owns affected cars with no option but to put themselves or someone else at risk of this car catching on fire - where else can you park a car that might catch on fire? its been 4 months since this recall has been issued nationally and no communicated resolution or targetted timing for resolution. Im concerned this recall will potentially start a gigantic car fire and harm someone, their homes, or their neighbors' property. I find it completely unacceptable that there's not even clear resolution timing for this problem which is essentially a ticking time bomb. People with these cars need help beyond what we're able to do as individuals. Thanks, andrew.

Urgent fire risk when parked recall as of September 23, 2025 and received this safeyy recall letter in November 2025 along with 'remedy is unavailable. ' called local BMW dealership today and no remedy and no clue as to when will be available. Urgent fire risk safety recall that is 4 months without a remedy?! is this acceptable? and no communication or updates available is very frustrating for a vehicle that is used daily for family, children, and work purposes. Please advise.

In September of 2025, I was notified twice by BMW via mail that my car is under recall. The NHTSA recall number is 25v636000. It is possible for water to contact and enter the engine starter. This could lead to corrosion which could cause a short circuit and ultimately a fire. They told me it would be fixed free of charge and I would be notified when the remedy was available. There were no such warnings or messages of the problem prior to being notified of this potential failure. Their mailed instructions told me to park the car outside which I did. My car was exposed to storms and hickory nuts from trees fell on my car causing damage. The extent of the damage was classified as the equivalent of "hail damage" and I had to pay $2000 out of pocket to a paintless dent repair shop to get the damage fixed. I called multiple dealerships back in October and they told me to check in February of 2026. It is now March and a remedy is still not available. I called multiple dealerships today, March 16th 2026, and they have all told me that parts are still not available. This is infuriating. I had to pay a significant amount of money due to a defect on BMW's part. I now park my car in my garage where it belongs. It is infeasible for myself and many others to park a vehicle outside. My safety is put at risk every day and I worry constantly that my vehicle will spontaneously combusts and burns my house down. BMW must make this right. I am seeking a timely resolution to this recall as well as a reimbursement for the cosmetic damage I was forced to repair.

My BMW 330i 2021 caught on fire while I was driving. Smoke came from the hood, and I open the hood and seen the fire, and I called the newark NJ fire department. See attached photo of the BMW after the fire.

I own [xxx] BMW vehicle affected by a safety recall for a defective engine starter relay that may corrode, overheat, and cause a fire. The recall notice dated November 2025 states the vehicle is not safe to drive, with no remedy available, rendering it unusable and hazardous. Recall n0. 25v-636. Under kansas lemon law (k. S. A. 50-645 et seq. ), I am entitled to a refund or replacement for this substantial defect impairing use, value, and safety, which BMW cannot repair. I demanded a full buyback at original purchase price, including fees, taxes, and incidental costs, or a comparable replacement. I requested a response within 10 business days. I sent this demand in November 2025 and have heard nothing since. The statute of limitations for lemon law claims in kansas is four years from defect discovery, per ucc provisions for warranty breaches. If unresolved, I want to pursue legal action for breach of warranty, lemon law violations, and negligence, seeking damages, fees, and costs. Please investigate BMW's handling of this recall and failure to respond. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving on the highway, my vehicle unexpectedly caught fire due to no fault of my own. Upon investigation, it appears the fire originated from a short in the rear window defroster wiring, which led to significant damage in the right rear c-pillar area, headliner, rear window, and rear deck. This event was not only hazardous to my physical safety but also deeply traumatic on a personal level. As someone who suffered severe burns as a child, experiencing a fire while operating a vehicle triggered a powerful emotional response. The trauma of the incident has had a profound impact on my mental health and sense of safety. I have always trusted BMW for its engineering excellence and commitment to safety, which makes this situation even more disheartening because they refuse to fix my vehicle.

I smelt and saw smoke coming from the back of my vehicle. I pulled over on to the left side of [xxx] bound. Then, I jumped out of the car to check the truck. I didn't see anything, then I popped the hood and still did not see anything visible. I then went back to the trunk to check it again, and that is when I saw flames pop out from the back seat area. It was in the area where the back DE-frost wires and some other wires are as well. Thank you, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving, my 2020 BMW 330i suddenly entered “drivetrain limited power” mode, severely restricting acceleration and overall performance. Upon diagnostic review, the cause was found to be a failure of the heat management module (hmm). This created a hazardous situation as the vehicle unexpectedly lost power while merging into highway traffic. Researching online, I’ve discovered numerous reports from other BMW owners experiencing the exact same failure on this model and other recent 3-series vehicles. This component failure is both common and costly, and yet there has been no recall or formal action from BMW to address it. Worse, the hmm is not covered under third-party powertrain warranties because it is considered an electronic part, leaving many owners with unsafe vehicles and no support. Given how widespread this issue appears to be — and the serious safety risk posed by sudden engine power loss — I urge the NHTSA to investigate this component for a potential recall or required manufacturer remedy.

The car has the fast wireless charging tray. I've attached a picture. The case for my phone has a small metal piece on the case. Its a regular case from amazon. The wireless charger works fine, but it's also heating the metal phone cases to the point where it starts a small fire. Its a huge fire risk if you're not careful. We tried another case and we had the same problem.

Failed component: driver side (left) exterior mirror available for inspection: yes safety risk: the mirror does not stay securely unfolded, requiring manual adjustment while driving, which creates a major distraction and increases the risk of an accident. If not manually secured, it shifts unpredictably due to wind resistance at city speeds, creating a dangerous blind spot that makes lane changes and merging hazardous. Glass isn't adjustable with buttons. The heating function is non-operational, which may impact visibility in cold/wet conditions. Problem reproducibility: the issue is persistent. Dealer or independent confirmation: the problem has not been diagnosed by a dealer, but has been check for dtc and there are no faults. Multiple reset attempts have been performed, including idrive reset, manual folding/unfolding, and a BMW battery reset procedure, cls was allowed to shut down fully, with no resolution inspection by manufacturer, police, or insurance: no warning lamps or symptoms prior to failure: none. The mirror was working perfectly before it failed suddenly with no warning signs, noises, or gradual malfunction. No known fault codes prior to the issue. Additional details: the mirror does not respond to electronic adjustments and must be manually repositioned. The glass will not adjust either unless by hand. When fully open or fully folded manually, makes a loud, forceful clunk and becomes slightly harder to move, but can still be adjusted moved with some effort. It opens far past the normal open position. In any other position other than fully extended or fully closed, it moves freely due to any external forces such as wind force while driving or lightly pushing it. The passenger-side mirror functions normally, including folding, heating, and glass adjustment. No obd error codes, warning lights, or system messages have appeared related to the failure. Mirror has not had any physical damage or abuse in any manner.

The vehicle has persistent issues with its software and safety systems, creating significant safety risks. The remote software upgrade feature fails to install, despite indicating it is “ready to install” with preparations complete. This prevents critical updates that could address safety and performance defects. BMW customer support was unable to resolve the issue, and a local dealership confirmed no hardware faults but could not address the software issue due to limitations as a non-BMW-certified service center. Several critical safety features also do not function properly. The blind spot warning system has never issued alerts, leaving the driver unaware of vehicles in adjacent lanes. The forward collision warning system has never activated, even in close proximity to other vehicles. The lane departure warning fails to consistently activate, while lane keeping assistance operates only intermittently, despite being designed to engage above 40 mph. Additionally, the parking collision warning and rear cross traffic warning systems have never provided alerts, even when obstacles or approaching vehicles are present. These malfunctions severely compromise the vehicle’s ability to prevent accidents and ensure safety. The vehicle also intermittently displays drivetrain failure warnings, stating the car can still be driven but should be serviced. Upon inspection, no issues were identified. Consistent fault codes for the active kidney grille shutters appear, but no check engine light is illuminated. These recurring warnings create uncertainty about the vehicle’s reliability and the accuracy of its diagnostics. The combination of these issues places the driver, passengers, and others at risk. A thorough investigation is needed to identify and resolve the root causes. All systems are available for inspection upon request.

Over time, the wiring harness going to the knee air bag(s) can rub against the metal support tubes for the instrument panel, chafing and damaging the wiring. Sib 65 20 22.

My car had been sitting across the street from my house for about 3 weeks after I had gotten it back from the body shop. It had been hit on the drivers side by a drunk driver when parked in front of my house. He took out six cars in a row. Heard a loud noise about 2 am - looked out the window and saw nothing. But then the fire trucks showed up after someone called them when they heard the bang. According to the firemen, it was probably caused by an electrical fire even though there were no visible flames. But the inside was filled with thick gray smoke which also came out of the trunk when they opened it. , the air bag was activated on the driver's side - the windshield was broken and the interior was a melted mess. The dashboard was melted on the driver’s side and the window was blackened. . The drivers side was where the damage had been from the accident. I do not think it coincidence. It seems I am not the only person whose BMW has spontaneously caught on fire. I did get BMW involved as far as sending documentation and talking to a rep. They of course were blameless. They did say they believe it was caused by an error made during a repair that allowed the rain water to get into the wiring. It had been raining hard for a couple days. But they could not say based on what I sent them if it was the body shop that did the most recent repair that made the error or it was done prior to that by another shop. But that they would not be investigating further. My much loved BMW been totaled and I will never what caused it.
